GAS-HOLDER.

SPECIFICATION forming part of Letters Ji-atent No. 757,887, dated April 19, 1904. Application filed June 11, 1903.: $eria1 No. 161,018. (No model.)

To all whom it may concern:

Be it known that 1, JOHN HENRY COKE, a citizen of the United States, and a resident of Black Diamond, in the county of King and State of Washington, have invented a new and Improved Gas-Holder, of which the following is a full, clear, and exact description.

This invention relates to a container for gases,particularly for illuminating-gases,such as acetylene. It may be employed in direct connection with the burner and other appurtenant parts of the lamp, or it may be separate therefrom with suitable communication with either one of a plurality of lamps.

The leading feature-of the invention resides in means for containing any desired quantity of gas under high pressure and for automatically reducing and regulating this pressure as the gas is fed to the point of consumption. This enables the gas, particularly in case of acetylene, to be used at a point removed from the point of generation, and by enlarging the capacity of the principal or high pressure reservoir the periods between the recharging of the gas-holder may be extended to any reasonable length.

This specification is an exact description of one example of my invention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a vertical section of the invention. Figs. 2 and 3 are sectional views illustrating the two valves for controlling the passage of the gas from the high-pressure reservoir to the point of consumption and illustrating particularly the lead between these valves, and Fig. 4: is a cross-section on the line 4 4 of Fig. 2.

The outer casing of the apparatus may be either integral or in the sections 10 and 11, as indicated in the drawings. According to this form the section 11 is the base-section and constitutes the high-pressure reservoir. .The top of this section is closed by a partition 12, suitably fastened in place, and the upper section 10 is fastened to the partition 12. Said upperv section may be provided, if desired, with an annular rabbet groove 14, threaded,

as shown, to facilitate the attachment of thelamp shade and globe, this construction presupposing the arrangement of the gas-holder as an immovable part of the lamp itself, and

in this case the element 15 may be taken as the gas-burner, and 16 the usual cock.

In the bottom or in any other suitable part of the section 11 an opening 17 is formed, this opening being surrounded by an inwardlydisposed boss 18, forming at its inner end the seat of a valve 19. The valve 19 opens inward and has its stem 20 extended into the boss 18 and surrounded by a spring 21, which bears between a nut or other enlargement on the stem and an interior wall on the boss 18.

22 indicates a plug or other suitable closure which is fastened removably in the opening 17 By means of these parts the section 11 is charged with the gas under high pressure.

To effect this charging, the plug 20 should be removed and a suitable gas-conducting tube (not shown) fastened in the opening 17. Upon turning on the gas the valve .19 will be raised and the high-pressure valve-reservoir suitably charged. Upon equalization of the pressures at the gas source and in thehigh-pressure reservoir the spring 21 will seat the valve 19. The before-referred-to gas-supply tube should of course be provided with an opening- Lugs 26 project downward from the v or opening 23, so as to close communication 1 from the high-pressure reservoir to'the space above the partition 12. ,The stem 29 carries an adjustable disk 31, and a spring32' bears between this disk and.the partition 12 and;

serves normally to open the Valve, 30. The

lower end of the stem 29 is loosely received in a suitable guide 33, formed on the bottom of the section 11 and projecting upward therein, and by this means and the means of the pin 27 the movement of the parts 29 and 30 is properly restricted. Upon the opening of the valve 30 gas from the high-pressure reservoir is charged into the space above the partition 12.

Formed integral with or fastened to the inner walls of the section 10, slightly above the partition 12, is an annular interior ledge 34, in which is fastened by any suitable means a diaphragm 35. Said diaphragm lies within and hermetically closes the space between the inner periphery of the ledge 34 and is connected at its center, by means of suitable fastening devices 36, with the upper end of the stem 29. As the pressure from the section 11 enters the spacebetween the partition 12 and diaphragm 35 the diaphragm is raised and the valve 30 is seated, thus cutting off the gas-supply. The instant, however, that the pressure below the diaphragm drops below the strength of the spring 32 the valve 30 will again be opened. The ledge 34 is formed with openings 37, and in said openings are screwed the threaded portions of valve-casings 38. Said casings may be of any desired number. Two are here illustrated by way of example. Said casings 38 have passages through them, and these are controlledby rotary plugs 39. To the plugs 39 arms 40 are suitabl fastened.

These arms are pivoted at their free ends to adjustable links 41, which pass inward and are connected to the under side of the diaphragm 35 by means of annular bands 42 and suitable connecting devices. Fastened to the connections 36 are springs 43, which bear down on the upper band 42 and tend to hold the diaphragm 35 depressed at this point, thereby throwing down the links 41 and arms 40. The

adjustment of the elements 39,40, and 41 is such that when the. diaphragm 35 and bands 42 are in their lower-positions the passages through the valve-casings 38 will be unobstructed. Therefore as the gas passes into the chamber between the partition 12 and diaphragm 35 it will flow through the valves 38, and this fiow will be continued until the pressure on the under side of the diaphragm is sufiicient to raise it. Thus not only will the valve 30 be seated, but the arms 40 will be rocked partly or wholly to close the valves 38. Figs. 2 and 3 show the two valves 38, with their plugs 39, in the proper position with respect to each other. Reference to either view will show that one of said plugs is slightly in lead of the other, and upon the beginning of the closing movement of the valve 38 one of said valves will be completely closed, while a slight orifice will be left open in the other. This provides for a gradual opening or closing of the gaspassages above the diaphragm and prevents any fluctuations at the burner or burners.

The valve-casings 38 have nipples 44, which project above the ledge 34 and are suitably fastened to gas-conducting tubes 45, which maybe either rigid or flexible, as desired. These tubes, according to the construction here shown, lead upward and inward to a chamber 46, in which the gas is allowed an expansion beyond that which takes place in the lowpressure chamberz'. 0., the chamber formed between the partition 12 and the diaphragm Said chamber 46 may be suitably fastened in the upper part of the apparatus. It is here shown as secured within a nipple 47 by means of a screw-cap 48. chamber 46 are formed with communicating orifices, and from the cap 48 a nipple 49 passes, with which nipple the cook 16 is joined, as illustrated.

In the operation of the invention upon'the charging of the high-pressure reservoir, as before described, the gaswill pass into the lowprcssure chamber through the orifices 25 and will be allowed a certain degree of expansion therein. 35 the valve 30 will first be closed; but the adjustment of the parts 39; 40, and 41 should be such that the valves 38 will not be wholly closed. The gas will therefore pass from the low-pressure reservoir into the chamber 46,

where a further expansion will take place,

Upon the raising of the diaphragm Said cap 48 and The commercial application and advantages 7 of my invention will, it is thought, he apparent; but in this connection I may point out that the principal utility lies in providing a gas-holder which may be charged from a gassupply and is yet wholly separate therefrom, so that the gas-holder may be removed any distance from the point of generation andf As such hook may be of any approved character, I have not illustrated the same in the drawings.

Various changes in the form, proportions, and minor details of my invention may be resorted to at will without departing from the spirit and scope thereof. Hence I consider myself entitled to'all such variations as may lie within the intent of my claims.
